The fifteen successor states of the Soviet Union are now facing the formidable task of restructuring their political and economic systems. One of the many positive effects of these radical political and social changes has been increased access to information-in libraries, archives, or from government sources. This Bibliography provides subject access to works on the region's social, political, and cultural development. While special emphasis is placed on books that examine the successor states' transition from communism to capitalism, other works, which concentrate on the Imperial Russian and Soviet periods, are also included. Most of the titles in the bibliography have been published since 1984. However, an effort was made to list important reference works, predominately bibliographies, regardless of their publication date. The bibliography consists of 3,172 entries; studies included are predominantly published in Western languages, primarily English. A comprehensive author index is included. This bibliography will assist both specialist and non-specialist by providing subject access to the wealth of publications currently available on the region.
